FREDERICK J. HUMPIIREY, OF KALAMAZOO, MICHIGAN.

WATER-*MOTOR.

SPECIFICATION forming part of Letters Patent No. 738,806, datedSeptember 15, 1903.

Application filed July 5,1902. Serial No. 114.412. (No modelJ To (tZZwhom it may concern:

Be it known that I, FREDERICK J. HUM- PHREY, a citizen of the UnitedStates, residing at the city of Kalamazoo, in the county of Kalamazooand State of Michigan, have invented certain new and useful Improvementsin Water-Motors, of which the following is a specification.

This invention relates to improvements in water motors, and particularlyto motors adapted for pumping purposes.

The objects of the invention are, first, to

provide an improved water-motor which is positive in its valve actionand one which is simple in its structure and operation and which willperform a maximum of work for the power consumed; second, to simplifythe valve mechanism for water-motors or similar engines; fourth, toprovide an improved construction of water-motor or similar engine inwhich the shock in reversing the engine shall be of no consequence.

Further objects will definitely appear in the detailed description tofollow.

I accomplish the objects of my invention by the devices and meansdescribed in the following specification.

The invention is clearly defined, and pointed out in the claims.

A structure embodying the features of my invention is fully illustratedin the accompanying drawings, forming a part of this specification, inwhich- Figure 1 is a detail longitudinal sectional view of a structureembodying the features of my invention, taken on line 1 1 of Figs; 2 and3. Fig. 2 is a detail cross-sectional View taken on line 2 2 of Fig. 1.Fig. 3 is a detail cross-sectional view taken on line 3 3 of Fig; 1.Fig. 4 is a detail longitudinal sectional view taken on a linecorresponding to the irregular line 4: 4, of Fig. 2. Fig. 5 is a detaillongitudinal sectional view taken on line 5 5 of Fig. 2. Fig. 6 is adiagrammat-ical View showing the circulation and the relative positionof the parts in operation.

In the drawings all of the sectional views are taken looking in thedirection of the little arrows at the ends of the section-lines.

Similar letters of reference refer to similar parts throughout theseveral views.

Referring to the lettered parts of the drawings, A is themotor-cylinder, A the pumpcylinder, and A a supporting-bracketconnecting and supporting the cylinders and their attached parts.

In the rnotor-cylinderA is a piston B, which is connected to the pump bya piston-rod B. The main-valve chamber (J, which is cylindrical, isarranged to one side of the pumpcylinder A, the central portion of thesame being of a slightly-reduced bore, as at G. In the main-valvechamber are reciprocating piston-valves C C, oppositely arranged, eachhaving three heads 0, fitting the small bore at the center, and p and qin the enlarged ends, all provided with hydraulic packings, that oftheheadqpointinginbothdirections. Chain bers are formed between theseveral heads.

Arranged to one side of the valve-chamber (J is an auxiliary or tripvalve chamber D,

inder A, which acts as a valve therefor.

I will now describe the parts and the connecting passages and ports indetail.

An inlet or induction passage G is provided, which terminates in anannular passage l), centrally located about the main-valve chamber andwhich communicates therewith by ports 19'. Ports a to either side of theports I) communicate with the annular passages (1, located to each sideof the annular passage b, and these passages are connected to the mainpassages a, leading to the ends of the motorcylinder and opening intothe same at points beyond the stroke of the piston B for the purpose ofcontrolling the same.- The ports a, are located far enough from theports I) to be .cut E therefrom by the packings of the head chamber ofvalve C to carry Water to and from the same in its operation, which flowis nected for exhaust.

0 when the valve 0 at that end is in its inner position and connectedtherewith when such valve 0 is in its outer position. (See Figs. 1 and6.) Exhaust or eduction passages E E, which unite in the mainexhaust-passage E, are formed in the enlarged part of the mainvalvechamber at each side of the center. These eduction-passages E arelocated far enough from the ports a to be cut off therefrom when a valve0 is in its outer'position and so as to be connected therewith when thevalve is in its inner position. (See Figs. 1 and 6.) It is thus clearthat the passages a serve the usual function of such passages inengine-cylinders. Centrally located about the chamber of theauxiliary ortrip valve D is an annular passage j. The passage j is connected to thetrip-valve chamber by suitable ports and to the induction-passage b by apassage j. A passage e at each side connects the annular port i to theouter end of ithe pistons of valve D to actuate the same,

as will be hereinafter explained. A passage 02. connects each end of theauxiliary valve chamber beyond the stroke of the valve D with thecorresponding main-valve -chamber at a point in the same far enoughremoved from the exhaust-port E, so that the packing of head p willdisconnect the same therefrom when the valve 0 is in the inner positionand near enough thereto to be connected with the exhaust-ports E bybeing embraced with said port E between the heads -0 and p of the valves0 when the valve is shifted to the outer position. The passage n'at eachside can therefore be connected altern'ately with pressure and exhaustto actu 'ate the auxiliary valve D, and that is one of their purposes.Small passages 0 connect from toward each end the motor-cylinder withthe corresp'onding main-valve chamber 0, the

passages opening into the motor-cylinder at points justwithin the strokeof the pistonhead and into the main-valve chamber at points which arealways between the packings of headsp and q of the valves 0, no matterwhat the position of the valves. These passages'c therefore connect themain cylinder with the auxiliary valve D at each end of thepiston-stroke by connecting the pressure t'ojthe passages 11.alternately through the valves G and insures the actuation of thevalve'D. The engine-cylinder acts as the engine-valve to the piston ofauxiliary valve D. The general arrangement of the ports and passageshaving been described, the operations of the structure will be pointedout.

With the piston and valves in the initial positions shown in thedrawings the water is admitted through the inlet or induction pipe G,passes into the main valve chamber through the ports I), and out throughthe ports a, to the ri ht in Figs. 1 and 6, leading to,

the end of the motor-cylinder. When the piston 13 passes the passage 0at the opposite end of the motor-cylinder, water is admitted through thesame into the main-valve chamber and through the passage n to thecorresponding end of the auxiliary-valve chamber. This, as the oppositeend of. the auxiliary chamber is then connected through the oppositepassage n to an exhaust-port E, (see the right of Figs. 1 and 6,) forcesthe valve D to the opposite end of the auxiliary valve chamber, whichconnects the passage '6 at that end to the passage j, the water passinginto the auxiliary-valve chamber through the annular portj and out ofthe same through the annular port t at the'right of Figs. 4 and 6, thevalves D being then in position to connect these ports. The directpressure of the water against the outer end of the opposite valve 0forces the same inward, cuts off the supply of water, and connects thatend of the motor-cylinder to the exhaust. The opposite end of themain-valve chamber is thusconne'cted through the' passages e, 'n, and cand the intervening portions of the chambers D and O to themotor-cylinder behind the piston, which by this time is in communicationat the opposite end of the exhaust, thus allowing the other valve 0 toshift outwardly. The position of the valves is then the reverse of thatshown in the drawings. This connects the opposite end of themotor-cylinder .to the exhaust-passage E at that end and connects thewater to the other end, whereby the action is reversed and the directionof the water through the several passages will be the reverse of thatdescribed. By this arrangement of valves and passages a gradual actionof the valves is secured, so that although their action is prompt it ispractically without shock or pounding.

It will be seen that as the valves are operated by the fullWater-pressure a prompt and sure action of the same is insured. It willfurther be noted that assoon as the position of the valves is shiftedthe motor-cylinder is free to exhaust through the passage a at that endof the motor-cylinder which is then connected to the exhaust, whichinsures a very prompt action of the motor.

I have illustrated and described my improved water-motor in detail inthe form preferred by me on account of its simplicity of construction. Iam aware, however,'that it 'is capable of numerous modifications andchanges in structural details without depart- IIO ing from my invention.

As suchchanges will readily appear to those skilled in the art to whichmy invention appertains, they are not here described.

Having thus described my invention, What I claim as new, and desire tosecure by Letters Patent, is-
